By means of generating function and partial derivative methods, we investigate and establish several general summation formulas involving two classes of polynomials. The general results would apply to yield some identities for the Pell polynomials and Pell-Lucas polynomials, and other general polynomials can also be recovered in this paper. 相似文献

A dinuclear copper(II) [(LCu)(MeOH)Cu(phen)(MeOH)]ClO4·NO3 macrocyclic complex (where H2L = 2,3-dioxo-5,6:15,16-dibenzo-1,4,8,13-tetraazacyclo-pentadeca-7,13-diene; phen = 1,10-phenanthroline) has been synthesized and characterized by means of elemental analysis and its i.r. spectrum. Its crystal structure has been determined by single-crystal X-ray diffraction. In the complex, both the copper ions are penta-coordinated and have a distorted square pyramid configuration. Magnetic susceptibility measurements show antiferromagnetic exchange interactions (J = –207.64 cm–1) between the copper(II) ions. 相似文献
